摘要：The present study investigated the contribution of RC (reinforced concrete) slabs to progressive collapse resistance of RC frame structures based on experiment and numerical calculation. During the progressive collapse of a RC frame structure under a center column removal, the damage of floor slabs was obviously observed. This indicates that the RC slabs have a significant effect to the progressive collapse performances of the frame structures. Based on the failure phenomenon of RC slabs and its resistance mechanism of progressive collapse, a simplified calculation model of progressive collpase resistance of RC slabs was proposed. The contribution to collapse resistance and the proposed model of RC slab were verified using experimental and numerical calculation results with and without slabs.
